Need some advice on ds18b20

Hope to seek advice i am trying use the common hardware ds18b20 thermometer, however i keep getting this error. thus i am not sure where did i go wrong, i tested with the other thermometer node it seem ok.

Hi, don’t use simulation, use debug loading.
Arduino library without simulation

Hi

Do you mean i load into arduino to debug instead?

Yes. Simulation mode has no way to emulate hardware like thermometer.
